摘要：Direct air capture (DAC) is a technology designed to capture CO2 directly from ambient air for carbon removal, while compressed air energy storage (CAES) involves compressing and storing air for later use in energy generation. However, diabatic CAES (D-CAES) systems, despite their commercial deployment, face limitations due to reliance on combustion, contributing to environmental pollution. Liquid-based DAC (L-DAC) systems offer negative emissions but are energy-intensive, often depending on electricity from natural gas plants. This study introduces an integrated system where L-DAC captures CO2 emitted by D-CAES during discharge, using electricity directly supplied by D-CAES, thus addressing energy and environmental concerns. Implemented in Aspen Plus (R) V11 and validated with literature data, the system's performance was assessed under various parameters. Results show a D-CAES round-trip efficiency of 59.27% and a levelized cost of electricity of $0.53/kWh. The cost of captured CO2 from the air is $259/tCO2. This study provides a comprehensive analysis and offers guidance for the sustainable commercial deployment of D-CAES while fostering advancements in DAC and energy storage integration.
